The next ones are numbers matrices expressions which can be evaluated for the program matrix.exe
(also with the Internet version), you should only copy the expressions, paste and evaluate (<INTRO> or the button Send).

Example 1, Calculates the determinant:

det([
           2	           5	           -3	           -2	
           -2	           -3	           2	           -5	
           1	           3	           -2	           2	
           -1	           -6	           4	           3	
])

Example 2, Calculates the inverse:

inv([
           1	           2	
           3	           4	
])

Example 3, Calculates the determinant:

det([
2	3	4	7	8
-1	5	3	2	1
0	0	2	1	5
0	0	3	-1	4
0	0	5	2	6
])

Example 4, Inverse of a complex matrix:

inv(           
[
           0+i	           1+2i	
           1	           3	
])

Example 5, Checking the inverse of a complex matrix,
the result is the identity matrix:

           
[
           0+i	           1+2i	
           1	           3	
]*inv(           
[
           0+i	           1+2i	
           1	           3	
])
